Characterization of Arm Autotomy in the Octopus, Abdopus Aculeatus (D’Orbigny, 1834)
Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Integrative Biology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Roy L. Caldwell, Chair Professor David Lindberg Professor Damian Elias Fall 2013 ABSTRACT Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Roy L. Caldwell, Chair Autotomy is the shedding of a body part as a means of secondary defense against a predator that has already made contact with the organism. This defense mechanism has been widely studied in a few model taxa, specifically lizards, a few groups of arthropods, and some echinoderms. All of these model organisms have a hard endo- or exo-skeleton surrounding the autotomized body part. There are several animals that are capable of autotomizing a limb but do not exhibit the same biological trends that these model organisms have in common. As a result, the mechanisms that underlie autotomy in the hard-bodied animals may not apply for soft bodied organisms. A behavioral ecology approach was used to study arm autotomy in the octopus, Abdopus aculeatus. Investigations concentrated on understanding the mechanistic underpinnings and adaptive value of autotomy in this soft-bodied animal. A. aculeatus was observed in the field on Mactan Island, Philippines in the dry and wet seasons, and compared with populations previously studied in Indonesia. -

The Ecology of Lizard Reproductive Output

Instead, we examine the rate of production (productivity of Biological Sciences, University of Reading, hereafter) calculated as the total mass of offspring produced in a year. We test ReadingRG6 6AS, UK whether productivity is influenced by proxies of adult mortality rates such as insularity and fossorial habits, by measures of temperature such as environmental and body temperatures, mode of reproduction and activity times, and by environ- mental productivity and diet. We further examine whether low productivity is linked to high extinction risk. Location World-wide. Methods We assembled a database containing 551 lizard species, their phyloge- netic relationships and multiple life history and ecological variables from the lit- erature. We use phylogenetically informed statistical models to estimate the factors related to lizard productivity. Results Some, but not all, predictions of metabolic and life-history theories are supported. When analysed separately, clutch size, relative clutch mass and brood frequency are poorly correlated with body mass, but their product – productivity – is well correlated with mass. The allometry of productivity scales similarly to metabolic rate, suggesting that a constant fraction of assimilated energy is allocated to production irrespective of body size. -

I Online Supplementary Data – Henle, K. & A. Grimm-Seyfarth (2020
Online Supplementary data – Henle, K. & A. Grimm-Seyfarth (2020): Exceptional numbers of occurrences of bifurcated, double, triple, and quintuple tails in an Australian lizard community, with a review of supernumerary tails in natural populations of reptiles. – Salamandra, 56: 373–391 Supplementary document S1. Database on bifurcation, duplication and multiplication of tails in natural populations of reptiles. We considered only data that were provided at least at the genus level and that explicitly originated from natural populations or for which this was likely, as either the authors indicated for other specimens that they were captive animals, or because museum series were examined (even if data were provided only for the specimens with accessory tails). We relaxed these criteria for pre-1900 publications and included also individuals without determination and data that were not explicitly stated as applying to wild individuals if such an origin was plausible. We extracted the following data (if available): species name, number of individuals with accessory tails, number of individuals with bifurcation, duplication, trifurcation, quadruplication, quintuplication and hexaplication, sample size, geographic origin (usually country but may also be oceanic islands), microhabitat, and the year of publication. Nomenclature follows Cogger (2014) for Australian reptiles and Uetz et al. (2019) for other species regarding generic names, name changes due to priorities and synonymies, and for subspecies identified in the source reference that have been elevated later to full species rank. Name changes due to splitting of taxa into several species were made only if allocation of the data to the new species was obvious from morphological or geographic information provided by the assessed source reference or was already done by other authors. -

Due to the severe threats that biodiversity encounters today natural history collections and the data they provide, have now a renewed interest. The collections of Nacional Museum of Lisbon were lost in a fire in 1978 with the loss of the type specimens collected from the centuries XVIII and XIX. Many of these collections still remain in the institutions to where they were sent making them the last remnants of the Lisbon musicological collections. Consulting the (AHMB) that survived the fire, has the objective of following the zoological scattering of the Lisbon Museum collections and their type specimens. This study has two main goals: 1) Contribute to its musiological valorization and with its data upgrading and increasing the biological information from poorly explored locations; 2) Provide a useful list of the musiological transferences from Museu Bocage and the possible type specimens that taxonomists and the rest of the scientific community can use to solve taxonomic problems that will have conservation implications. -

Kupe, a mountain at the southern edge of the Cameroonian Highlands. This work resulted in the sampling of 48 species, including 38 amphibian and 10 reptile species. By combining our data with prior survey results from higher elevation zones, we produce a checklist of 108 species for the greater Mt. Kupe region including 72 frog species, 21 lizard species, and 15 species of snakes. Our work adds 30 species of frogs at lower elevations, many of which are associated with breeding in pools or ponds that are absent from the slopes of Mt. Kupe. We provide taxonomic accounts, including museum specimen data and associated molecular data, for all species encountered. -
